摘要:
家用负荷中多为感性负载,会产生各种电能质量问题,损耗家用电器,减少其使用寿命。在户用型离网系统中,逆变器控制技术是关键。在户用型微网的结构下,以离网逆变器为研究对象,主要研究户用型离网直流母线电压波动以及负载启动瞬间对供电电能质量的影响。通过电压电流双环控制,改善输入负载的电能质量,以降低对直流侧电压的要求。通过Matlab Simulink仿真验证,比较系统开环与闭环的波形图,并进行谐波分析。结果表明,所提出的双环控制策略,能够改善逆变器的输出电压电能质量。
Abstract:
Off-grid systems for household are proposed to solve problems that population in remote areas lacks electricity.In an off-grid home,electronic devices can result in poor power quality issues.In this paper,proposed a control strategy which uses a dual-loop control of the output voltage and output current decoupling feedback to get higher power quality.The Matlab/Simulink software has been used to carry out the simulations.In the same system topology, compared results uncontrolled and controlled.The results compared analyzing their corresponding current and voltage waveforms,and the THD values.The simulation results show that the proposed control strategy can achieve nice power quality.
